THOMAS HOLMES, OF CHELSEA, MICHIGAN.

NUT-CRAGKER.

SPECIFICATION forming part of Letters Patent No. 425,428, dated April 15, 1890.

Application tiled August 3l, 1889. Serial No. 322,610. (No model.) l

To all whom t may concern:

Be it known that I, THOMAS HOLMES, a citizen of the United States, residing at Chelsea, in the county of lVashtenaw and State of Michigan, have invented a new and useful Nut-Cracker, of which the followin gis a specilcation.

The invention relates to improvements in nut-crackers.

The object of the present invention is to provide a nut-cracker of simple and inexpensive construction capable of exerting great force, sufficient to crack the hardest nut without liability of smashing the nut too much for use.

The invention consists in the construction and novel combination and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective View of a nut-cracker constructed in accordance with the invention. Fig. 2 is a side ele- Vat-ion, a lportion being broken away to show the construction of the lower end of the operating-lever.

Referring to the accompanying drawings, A designates the base of the machine, which is designed to be secured to a table or other suitable standby screws or the lile,`which pass through perl1 oraticns o. in enlarged corners or feet o. of the base A. At the ends of the base A are upward-extending ears a2 and a3, between which are pivoted an operating-lever B and a cracker-arm C.

The operating-lever is provided at its lower end opposite the pivotal point with a curved recess l), which receives the pointed free end c of the cracker-arm C, and when the lever is raised the lower portion of the recess Z2 engages the end c and raises the cracker-arm, and when the operating-lever B is lowered the upper wall of the recess engages the end c and forces the cracker-arm downward to within a short "distance of the base, an approximately pyramidal projection D being provided to prevent the cracker-arm descending too far and to preserve a nut from too much compression. By this arrangement a pressure sufficient to crack the hardest shell is brought upon a nut.

The opposing faces of the cracker-arm C and the base are provided with serrations a and c2, which prevent the nut slipping, and the cracker-arm is also slightly curved, and when it is resting upon the projection D a triangular opening is formed between it and the base, which will accommodate varioussized nuts and permits the amount of compression to be regulated.

The extreme lower end of the operating-lever B is provided with a shoulder h', which engages with the base A and prevents the lever being raised too much, and the crackerarm C is sufficiently long to project between the ears a? when depressed to prevent the said arm turning to one side under extreme pressure.

From the foregoing description and the accompanying drawings the construction, operation, and advantages of the invention will readiljT be understood.

l. In a nut-cracker, the combination of the base, the cracker-arm pivoted to one end of the base and being slightly curved throughout its entire length and adapted to form an approximately triangular opening between it and the base when its free end rests upon the latter, and the operating-lever pivoted to the other end of said base and adapted to engage the free end of the cracker-arm, substantially as described.

2. In a nut-cracker, the combination of the base, the cracker-arm pivoted to one end thereof, and the operating-lever pivoted tothe other end of the base and provided with a recess to receive the free end of the cracker-arm, substantially as described.

3. In a nut-cracker, the combination of the base, the cracker-arm pivoted to one end thereol", the operating-lever pivoted to the other end of said base, and the projection limiting the downward movement of the cracker-arm, substantially as described.

il. The combination of the base provided at its ends with ears, the cracker-arm pivoted between the ears at one end of the base, the operating-lever pivoted between the ears at the other end et the base and provided with a curved recess to receive the tree end of the cracker-arm, and a projection to limit the free end of said arm, substantially as described.
